Earthquake in Illinois could portend an emerging threat
To the surprise of many, the earthquake on April 18, 2008, about 120 miles east of St. Louis, originated in the Wabash Valley Fault, not the better-known and more-dreaded New Madrid Fault in Missouri's bootheel. The concern of Douglas Wiens, Ph.D., and Michael Wysession, Ph.D., seismologists at Washington University in St. Louis, is that the New Madrid Fault may have seen its day and the Wabash Fault is the new kid on the block. (2008-04-24)

Can your dog predict an earthquake? Evidence is shaky, say researchers

Shaking up megathrust earthquakes with slow slip and fluid drainage
Megathrust earthquakes are the most powerful type of earthquake, occurring at subduction zones -- where one tectonic plate is pushed beneath another. By contrast, slow slip events (SSEs) release seismic stress at a lower rate than large earthquakes, re-occurring in cycles. These processes can take place along the megathrust and other planes of weakness in response to loading, releasing low frequency seismic waves. Researchers in Japan consider the fluid drainage processes that can occur from SSEs and their impact on seismic activity. (2018-04-09)

Study quantifies potential for water reuse in permian basin oil production
Hydraulic fracturing has once again made the Permian Basin one of the richest oil fields in the world. But the improved reserves come with some serious water management issues. Drilling for oil uses water upfront, and brings up large volumes of water that need to be managed. The study, published in Environmental Science & Technology on Sept. 6, found that recycling the water produced during operations at other hydraulic fracturing sites could help reduce potential problems associated with the technology. (2017-09-06)

Analysis of major earthquakes supports stress reduction assumptions
A comprehensive analysis of 101 major earthquakes around the Pacific ring of fire between 1990 and 2016 shows that most of the aftershock activity occurred on the margins of the areas where the faults slipped a lot during the main earthquakes. The findings support the idea that the area of large slip during a major earthquake is unlikely to rupture again for a substantial time. (2018-02-14)

SMU study finds earthquakes continue for years after gas field wastewater injection stops
Shutting down oil and gas wastewater injection wells may not stop human-induced earthquakes quickly, say seismologists at Southern Methodist University, Dallas. The scientists analyzed earthquakes at DFW Airport that began in 2008 and found that even though wastewater injection was halted after a year, earthquakes continued for at least seven more years. They concluded that high-volume injection, even for a short time, can induce long-lasting seismicity when it's near a critically stressed fault. (2018-02-13)

Parkfield segment of San Andreas fault may host occasional large earthquakes
Although magnitude 6 earthquakes occur about every 25 years along the Parkfield Segment of the San Andreas Fault, geophysical data suggest that the seismic slip induced by those magnitude 6 earthquakes alone does not match the long-term slip rates on this part of the San Andreas fault, researchers report November 28 in the Bulletin of the Seismological Society of America (BSSA). (2017-11-29)

Southern Italy: Earthquake hazard due to active plate boundary
Tectonically, the Mediterranean is extremely active and thus threatened by natural catastrophes. Over the last few years an international team of researchers with participation of scientists from GEOMAR Helmholtz Centre for Ocean Research Kiel has intensively studied the seafloor south of Sicily and Calabria. In their study, now published in the international scientific journal Earth and Planetary Science Letters, they found evidence for recent tectonic activity on a plate boundary, which can cause strong earthquakes.
